Obviously I can't do grid references but.. if you stand with your back to Carreg Samson and look towards St.Davids head its probably south west. There is a lot of stones and tumulus in the Strumble Head/St.Davids Head/Havordfordwest triangle. In a local report (somerset) which I read the other day, someone described a particular area as sepulchral, obviously uneasy with the terminology - sacred landscape. Well it seems to me that this part of Wales has the same feel to it.
